Hi,

Are you running with Security Enhanced Linux Enabled or Disabled ?   If 
so try disabling it at least temporarily.  Some people will say set to 
permissive mode rather than disable, but specifically for NIS I have 
seen different behaviour between permissive and disabled.  If this works 
others may be able to assist you with getting SE Linux worknig with NIS.

Are you running a Firewall ?
